If you have an existing website and you want to add category to your blog posts links (e.g. by using: /%category%/%postname%/ in Settings > Permalinks) then your visitors 
will most likely run into page not found errors. This plugin checks for such post links and redirects the visitor using permanent (301) redirect to the correct /Category/Permalink link IF the permalinks are setup.
This plugin assumes that you have previously used /%postname%/ in your Settings > Permalinks.

Permalinks to Category/Permalinks

While it may seem trivial, switching from permalinks to a prefix using a category is tough. Slavi's plugin works just as expected and works out of the box. Definitely recommended.

Works as expected, thanks!

The plugin automatically redirects users who have accessed a blog post link without the category to the one which has the category and therefore avoid …

The Link Fixer Plugin (note the name change from Permalink Finder) detects when WordPress cannot find a permalink. Before it generates the 404 error the plugin tries to locate any posts with similar words. It does this by searching through the database trying to find any of the word values from the bad link. It takes the best match and then, rather than issuing a 404 error, it sends back a redirect to the correct page. 
Users will see the page that they are looking for, and search engine spiders will see the 301 redirect and update their databases so that the page appears correctly in searches.
The configuration panel allows a user to select how the plugin finds a missing page. The plugin counts the number of words that match to a post. By default, a two word match is sufficient to cause a redirect to the found page. False positives are possible, especially if the user selects a one word match. Increasing the number of words, however makes it unlikely that the plugin will ever find a match. You may eliminate numbers from the search. You may specify that a list of common English words like “the”, “and”, “who”, “you”, etc., not be considered in finding the correct permalink.
Optionally, the plugin will redirect hits on index.html, index.htm, and index.shtml to the blog home page. This is useful when a website previously used a non-php home page.
If WordPress detects a 404 error on robots.txt, sitemap.xml, crossdomain.xml, favicon.ico, or apple-touch-icon.png it will provide a default version.
The plugin will also optionally keep track of the last few 404’s or redirects. This is useful to find out what pages are missing or named badly that keep causing 404 errors or forcing redirects.
